The diagram is a derivative from the map 2.5. Green (vegetated) and blue (water) urban areas have been extracted from the Urban Atlas product, i.e. values for 369 core cities are available. The considered area is the UMZ inside the core city area (defined in Urban Atlas). The selection of classes contained in the green and blue urban areas is based on their relevance for the Urban Heat Island effect. The following selection has been made, all classes marked in green are components of the green and blue urban areas:

CODE

Urban Atlas classes

11230

Discontinuous Low Density Urban Fabric (S.L. : 10% - 30%)

11240

Discontinuous Very Low Density Urban Fabric (S.L. < 10%)

14100

Green urban areas

14200

Sports and leisure facilities

20000

Agricultural areas, semi-natural areas and wetlands

30000

Forests

50000

Water bodies

Those classes were extracted from the Urban Atlas, their area summed up and its share in relation to the total area of the city (core city-UMZ) calculated. For the map production the values were classified into 4 classes and presented as different colours.

The diagram is produced by summarising the single city information into country related information.

Appreciate wildlife, but be sure to watch wild animals from a distance and avoid feeding them. Remember, the scent you leave when you touch a nest or a lair may scare the parents off for good. Instead of touching, try to find out more about them and maybe even discover how you can contribute to their protection.
